Veteran real estate executive Thomas Weeks will join Rockefeller Group in New York City as EVP and head of development, effective September 30. Previously, Weeks was executive general manager for Lendlease Development, based in Chicago.

Reporting to Rockefeller Group President and CEO Daniel J. Moore, Weeks will shape and pursue the company’s development strategy, which anticipates increasing activity in existing markets and growing the platform into new U.S. markets.

“We are thrilled to have Tom join the company as our first head of development,” said Moore. “We’re poised to take our business to the next level and I’m confident that under Tom’s leadership, we’ll redefine and manifest what we’re capable of as an organization.”

Over a career spanning 25-plus years, Weeks has held senior leadership roles with several of the nation’s most active developers and construction firms. These include Clayco and Related Midwest, the latter as president for seven years.
